3/6

Key Takeaways

  • 1% rate increase on $187K adds ~$122/month.
  • Tax reassessment after renovation: 30-80% increase.
  • Model 3-5% expense growth vs 2-3% rent growth.

Cash flow compression from rising rates and expenses is a slow-burn risk that can make profitable portfolios unprofitable.

Interest Rate Risk

A 1% rate increase on $187,500 adds ~$122/month. At 7% the payment is $1,248; at 8.5% it is $1,443. With $1,500 rent, cash flow turns negative above ~8.2%.

Expense Inflation

Tax reassessment after renovation: 30-80% increase. Insurance costs up 20-40% since 2022. Model expense growth at 3-5% and rent growth at 2-3%.

Protection Strategies

Buy in markets with strong rent growth. Target value-add rent opportunities. Build $200-$300/month reserves per property. Include 2-3% annual rent escalation clauses. Refinance to lower rates when markets allow.

Common Pitfalls

Not accounting for tax reassessment after renovation

Risk: Taxes jump 30-80%, turning cash-flowing property into break-even

Correction

Research local reassessment triggers and include post-renovation tax increase in analysis.

Assuming insurance costs will remain stable

Risk: Insurance costs rising 20-40% since 2022 can eliminate cash flow margins

Correction

Model 5-10% annual insurance increases and shop coverage annually.
